Judge Lynch jailed Hennigan for 18 months for insulting and making racist slurs to a black Caribbean mother in Harlow, Essex.

The QC has since "apologised unreservedly for her remarks".

She also told investigators she "deeply regretted the incident" and said her "remarks were a momentary lapse of judgment which should have never happened".

An investigation report sent by the JCIO to one of the complainants states: "Although the Lord Chancellor and Lord Chief Justice considered HHJ (Her Honour Judge) Lynch's remarks to be inappropriate, they did not find that they amounted to misconduct or warranted disciplinary action."

It added: "With the agreement of the Lord Chancellor, the Lord Chief Justice therefore advised HHJ Lynch to ensure that she responded appropriately in court at all times."
